How do we detect moisture in flat roofs?

  • Tector's wireless sensors talk directly to our web-based app, giving you real-time data and alerts.
    We use AI to keep an eye on moisture levels 24/7.
    This keeps you in control, no matter where you are.

The challenge

We all know that deciding to construct a flat roof comes with its risk.

  • On average, it amounts to 3.31% of total construction costs.
  • We have detected more than 1 damage during construction on average
  • Statistics show that more than 50% of projects have defects in their flat roof leading to critical disruptions after handover.


Defects arise due to

  • Workmanship
  • Rush during construction & lack of quality assurance
  • Technical design issues
  • Material & other subcontractors accidentally break the roof felt.


On top of being a risk area, the risk of water ingress on a flat roof increases with:

  • Solar panels (adds weight and/or penetration to the surface)
  • Green/blue roofs & roof terrace (adds layers on top of the structure which complicate leak localisation)
  • Technical installations (adds many penetrations and complications that can be difficult to seal 100%)

The solution

  • Install sensors every 15-25 m2 close to risk areas (depends on complexity of the roof).
  • The sensors are installed underneath the roof felt and insulation, but on top of the waterproofing membrane.
  • The sensors are installed by the people on site in less than a minute per sensor.
  • This gives an immediate warning as soon the roof felt has a defect and water ingresses into the insulation layer - before it becomes expensive to repair and damages the construction underneath.


Benefits of moisture sensors

  • A cheaper and more efficient continuous quality assurance of the work done on the roof
  • Immediate detection enabling repair costs up to 95% cheaper than later detection
  • Enhanced focus on quality throughout the project and transparency enabling better collaboration & less conflicts
  • Increased insurability & savings of up to 50% on excess related to water ingress


Flat roof moisture sensors

  • Spot on accuracy: Tector’s AI wireless sensors provide accuracy and reliability far beyond manual measurement methods.
  • Long performance: built to last up to 10 years, so you don’t have to worry about replacements.
  • Easy placement: Designed to fit anywhere, our sensors go where others can’t, ensuring no spot is missed.
  • Saving money: Say goodbye to costly manual checks. Tector’s system saves you time and cuts labour costs.
  • Real-time data: Get instant data on moisture levels so you can act fast and make smart decisions.
